Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current electronic devices, such as smartphones and smartwatches, often automatically turn off the display when in use, causing inconvenience to users and affecting their experience, as the display is not easily accessible during operations like calls.
Innovation Solution
An information processing method that uses sensors to determine the distance between the user's body and the device's display, switching the display from a low-power state to an operational state when the user is within a predetermined distance threshold, ensuring the display is accessible and usable.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If the display automatically turns off when the user approaches during a call, then power consumption is reduced, but user convenience deteriorates as the display is not easily accessible during operations
Solution Approach 1:
The display module dynamically switches between low-power-consumption state and displaying-operating state based on real-time sensing of user approach distance. When the user approaches within the distance threshold, the display transitions to the operating state for easy access during calls; when the user moves away, it returns to low-power state, thus adapting to different usage scenarios.
Solution Approach 2:
The system uses a sensor to detect the user's approach and provides feedback to the control unit, which then adjusts the display state accordingly. This closed-loop feedback mechanism ensures the display is accessible when needed (during calls) while consuming minimal power when not in use.
2Ease of operation
If the display remains on during operations, then user convenience is improved with easy access to information, but power consumption increases
Solution Approach 1:
The display operates in a dynamic manner, switching between on and off states based on user proximity detection. During call operations, the display remains on for accessibility; when the user moves away, it turns off to conserve power, thus balancing usability and energy efficiency.
Solution Approach 2:
The sensor continuously monitors user proximity and provides feedback to the control unit, which adjusts the display state in real-time. This ensures the display is on only when the user is close and needs it, minimizing unnecessary power consumption while maintaining accessibility during operations.
3Ease of operation
If the display switches state based on distance threshold, then user experience is improved with rapid activation, but device complexity increases due to additional sensing and control mechanisms
Solution Approach 1:
The system achieves automatic display state switching through the sensor detecting user proximity and the control unit processing this information. The device serves itself by automatically adjusting the display state based on user needs, eliminating the need for manual user intervention and providing rapid activation.
Solution Approach 2:
The sensor acts as an intermediary between the user and the display system, detecting user proximity and transmitting this information to the control unit. This intermediary mechanism enables automatic display activation without requiring complex user interactions, improving activation speed while keeping the added complexity manageable.
